Why any dipole placed in an uniform electric field only rotates about its position and does not move?

When an electric dipole is places in a uniform electric field , it experiences no force as the electric force on both the negative and the positive charge are equal in magnitude but opposite in direction so they cancel out. But , it experiences a torque(couple) and hence it rotates.

since net force is zero in uniform electric field on dipole so there is no movement of com but there is a torque generated which will make it move in a rotational motion
